Diagnostic methods for esophageal tumors

In order to enable everyone to receive treatment, I believe many friends want to detect this cancer early and receive treatment early. Let’s take a look at the diagnosis methods of esophageal tumors.

The diagnosis of esophageal tumors is as follows:

1. Examination of esophageal function:

1) Esophageal motility test: A) Esophageal manometry, suitable for patients suspected of esophageal motility disorder; B) Acid clearance test, used to measure the peristaltic efficiency of the esophageal body to eliminate acid.

2) Gastroesophageal reflux measurement: A) Esophageal acid perfusion test; B) 24-hour esophageal pH monitoring; C) Lower esophageal sphincter manometry test.

2. Imaging diagnosis:

1) X-ray barium meal examination: It is one of the important means to diagnose esophageal and cardia tumors. It can provide reliable data for the study of early esophageal cancer. Combined with cytology and esophageal endoscopy, it can improve the accuracy of esophageal cancer diagnosis. X-ray barium meal examination of esophageal cancer not only determines the location, length and degree of obstruction of the lesion, but also determines whether the esophageal lesion has invaded and the scope of invasion.

2) CT examination: CT scan can clearly show the relationship between the esophagus and the adjacent mediastinal organs, but it is difficult to detect early esophageal cancer. Combining CT with X-ray examinations can help improve the diagnosis and staging of esophageal cancer.

3. Esophageal exfoliative cytology examination:

The esophageal exfoliative cytology examination is simple, easy and safe to operate, causes little pain to the patients, and has an accuracy rate of over 90%. It is an important method for large-scale screening of esophageal cancer.

However, patients with esophageal cancer who have bleeding or bleeding tendency, or those with esophageal varices should not undergo esophageal cytology examination; patients with deep esophageal ulcers on esophageal cancer X-rays, or those with hypertension, heart disease, and late pregnancy should be examined with caution; patients with poor systemic condition and excessive weakness should have their general condition improved before examination; patients with acute inflammation of the upper respiratory tract and upper digestive tract should have the infection controlled before examination.
